tljh-config tries HTTPS against 127.0.0.1, generating spurious warnings #757

You can get these warnings when using tljh-config, and I figure it would be preferable if we can handle this better in some way. I'm not sure how.

$ sudo tljh-config reload

Hi there, I'm a teacher at Universitat Oberta de Catalunya. We have deployed a TLJH for a programme in our studies. After trying to update our initial configuration (a custom configuration to clone a repository each time a user spawns a new server if the repo is not there), with sudo tljh-config reload hub we got stuck in an infinite loop of these warnings, and the server no longer launches.

Also, systemctl status jupyterhub.service shows: 

● jupyterhub.service

We are a couple of days ahead from needing this working, does anyone have any tip?

Thanks!
